Specific features of electrophysical properties of multicomponent heterogeneous systems

Abstract

Electrophysical properties of multicomponent heterogeneous systems containing polar liquid phase and electrically active inclusions are investigated while the study of human blood. It was found that the examined biological system has electret properties which are related to accumulation of interphase charges in the presence of inner electric field. Special attention is paid to the analysis of change of structure of water component in plasma near the interfaces. The existence of low-temperature current maximums whose dynamics is the same for all groups of blood and high-temperature current maximums which characterize individual properties of the biofluid in the range of temperatures (20-220) °C has been established. For the first time electrophysical parameters that describe physical properties of human blood thoroughly are determined.
